ABSTRACT:
This invention relates to lubricating oil additives, and to lubricating oil compositions, their method of preparation, and use. More specifically, this invention relates to several novel lubricating oil additives and compositions which contain a tungsten compound and an antioxidant, namely aminic antioxidants such as a secondary diarylamine or an alkylated phenothiazine. The use of the tungsten compound with the secondary diarylamine and/or the alkylated phenothiazine provides improved oxidation and deposit control to lubricating oil compositions. The lubricating oil compositions of this invention are particularly useful as crankcase and transmission lubricants, gear oils and other high performance lubricant applications.
